I have an SUNSDR2 PRO and this unit have started to develop strange behavior, on 15 m, only 15 m, the signals get distorted and the noise floor rise like 30-40 db then you apply a signal, tested with SSG at -80 dbm same thing, on all other bands it is clean.
no I have try everything same thing on only 15 m, also you can hear the FT8 signals gets distorted and if i inject a CW carrier and listen in CW or SSB mode it is also distorted in the beat tone and only on 15 m
